Here's how to set up wifi on the Bone.

bone$ connmanctl
Error getting VPN connections: The name net.connman.vpn was not provided by any
connmanctl> scan wifi
Scan completed for wifi
connmanctl> services
*AR RHIT-OPEN            wifi_987bf3d2e45e_524849542d4f50454e_managed_none
    BeagleBone-DF34      wifi_987bf3d2e45e_426561676c65426f6e652d44463334_managed_psk
    eduroam              wifi_987bf3d2e45e_656475726f616d_managed_ieee8021x
    DIRECT-da-HP M132 LaserJet wifi_987bf3d2e45e_4449524543542d64612d4850204d313332204c617365724a6574_managed_psk

Here is a list of all the access points the Bone can see. Let's pick RHIT-OPEN and connect to it.

connmanctl> connect wifi_987bf3d2e45e_524849542d4f50454e_managed_none

If you get a "Not registered" error when trying to connect, run this:

connmanctl> agent on

Fortunately connmanctl has TAB completion, so you don't have to type the whole name, just type a few characters and then hit TAB. Once connected you can configure it so it will stay connected.

connmanctl> config wifi_987bf3d2e45e_524849542d4f50454e_managed_none --autoconnect yes

Then you can quit.

connmanctl> quit

See if you can hit google.

bone$ ping -c2 www.google.com

It looks good.

More Details

Yes can see help in connmanctl.

bone$ connmanctl
connmanctl> help

quit                                  Quit
